Example of adding custom otel spans to python sdk

[marsh flume]

I saw an example of using custom spans with go, but was wondering if there is an example with the python sdk?

Sure!

import anyio
from opentelemetry import trace
import dagger

tracer = trace.get_tracer("my_module")


@dagger.object_type
class MyModule:
    ...

    @function
    async def test_all(self):
        """Run the test suite on multiple Python versions."""
        async with anyio.create_task_group() as tg:
            for version in self.supported_versions():
                tg.start_soon(self.test_version, version)

    async def test_version(self, version: str):
        with tracer.start_as_current_span(f"Test Python {version}"):
            await self.test(version).default().sync()
